Perhaps I'm wooed by fad ;), anyway, I read about using PS2 mouse and
keyboard should be better than using USB mouse and keyboard, perhaps to
shared IRQ issues or something similar. USB might be an issue?

Did you think of making several equal Envy24 cards (30,-€ at Ebay) one
virtual card? I didn't do it with my cards, but I guess this should
work, resp. I guess you're searching for USB, because you're using a
laptop? I guess there're Envy24 USB devices too and they are very cheap,
but full duplex etc..
